What we check first in Blackwood
In Blackwood the highway authority for local roads is Caerphilly County Borough Council. We confirm whether the ground is adopted highway before quoting, because semi-automatic bollards on a public footway need its agreement first.
If your site in Blackwood is listed or inside a conservation area, check with the local planning authority (Caerphilly County Borough Council) before choosing a finish — heritage settings often favour cast iron or painted steel over stainless.
Reinstatement around the collar has to be firm, because the post is pushed down by foot and any movement in the surround soon shows as cracking. Because the cassette houses both the post and its strut mechanism, the pit is deep and must stay dry.
- Check land ownership; bollards on public highway need the highway authority's agreement.
- Keep clear gaps of typically at least 1,000–1,200 mm where pedestrians pass between posts, referring to Inclusive Mobility guidance.
From survey to handover
Excavate the pit
The surface is cut and the pit dug to the cassette depth plus a drainage layer, by hand near services.
Set the cassette
The cassette is set plumb and flush with the finished surface, connected to drainage and concreted in. The strut is fitted or released only as the manufacturer instructs.
Test and show users
The post is cycled several times to check it rises fully, locks at both heights and lowers smoothly. Users are shown how to operate it and to keep clear of the head when it rises.
Choosing the right spec
| Option | Detail |
|---|---|
| Gas strut or spring assist | Most models use a gas strut; some use springs. Both store energy to raise the post when unlocked. |
| Duty level | Light-duty domestic models and heavier commercial versions with stronger cassettes and posts. |
| Height and diameter | Raised heights commonly around 500–900 mm and diameters around 100–200 mm, depending on model and duty. |
What affects the quote
Our Wales guide prices are a starting point; the survey in Blackwood firms them up. What tends to move them:
- Number of posts and keyed-alike locks
- Domestic or commercial duty model
- Excavation depth and services in the way
Looking after them
Look into the cassette periodically for water or debris, and lubricate the lock and latch as the manufacturer suggests. In winter, keep an eye on the lid after frost or snow; ice around the head can stop the post rising, and forcing the key or the post at that point damages the latch.
We can also service, repair or replace existing posts anywhere in Blackwood.

How is a semi-automatic bollard different from an automatic one?
An automatic bollard is powered and controlled by a panel, loops and access devices. A semi-automatic one rises on its own when unlocked but must be pushed down by hand. It needs no electrics, which keeps installation simpler.
Why has my semi-automatic bollard stopped rising fully?
Usually because the gas strut has lost pressure, or debris and water in the cassette are slowing it. Check and clean the cassette first. If it still stops short, the strut needs replacing.
